Is There a Replacement for the Doorbell Camera?

The first person who rang my doorbell while I was not at home. Was of all people my landlord who's from Dublin. And eventually he heard something like this and it kind of makes it kind of face the lizard. Where they make it seem as easy as you see in those ads, George, no right, No, You know what? If it's not wired, if it's not on the Wi-Fi then it doesn't work. This becomes very important in a world where cops are really driving to the net to be able to get access to people sometimes that's just as simple as going do you have any footage of  the satm over here?"
